Application led .Tune 23, 1922. Serial No. 570,388.

T all whom t may con-cem Be it known that we, JOHN. Q. SHERMAN and ALBERT lV. METZNER, citizens of the United States, and residentsof Dayton, in

the county of Montgomery and State of- Ohio, have invented certain new and useful improvements in Manifolding Typewriters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to typewriters which make an impression upon and through a number of copies at one and the same time.

l5 The usual method of making pluraldcopies is either to employ carbon paper or else to employ a printing ribbon which isv wound \back and forth between the various webs to be imprinted.

Itk is the object of our invention to providel a penetrating type which of itself will penetrate an'd mark as many webs of paper as are desired, and to provide means for inking the type.

In the modification shown in. the' drawings, the invention is shown as applied to an Elliot-Fisher billing machine, although it will be understood that the invention may be applied to a number of dii'erent forms of otypewriter` I We accomplish thel objiects ci our invention by that certain construction and arl rangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings, f

Figure 1 is a detail` side elevation partly broken away showing the essential features of oui1 invention.

Figure 2 is a detail of the type member .1o and stripper finger. Figure 3 isa detail elevation of one of the pins making up the type member.

Figure 4 is a View showing the form taken by the letters printed by our invention.

Figure 5,is a top plan view showing the ink well and the recimocatingfeltcarrier, this carrier correspond-ing to the ribbon carrier of an Elliot-Fisher-machine.

Figure 6 is aplan view of the inking felt.

Figure 7 isa side elevation showing a maniol-ding, or billing machine and the' mounting point of our inking devices.

Referring to the drawings, the frame of -a billing machine is shown at 1, on which 55, is mounted the typewriter As in the Iin the paper in the desired design, each hole usual machine, this typewriter moves bodily in two directions, and it will be understood that the devices used in vconnection with the type must move with the machine, whereas in applying our machine to movable carriage machines, the inking devices will be stationary.

Each type .bar 3 o the typewriter is formed at its -end with the desired letters or symbols, made up of pointed pins arranged to make up the Iletter by the projecty ing pin points. It is preferred that these pins be made with Shanks 4 and points 5, which are formed with ink carrying grooves 6, so as to take ink through any number of 70. webs of paper which the pins will puncture.

ln making an 'impression the type barsy are operated as usual and the pins thrust into the paper. rThey willV make smallholes being surrounded by a rim which is inked,

thereby making a non-erasable, but quite neat typewritten impression on all webs without the use of carbon paper or multiple printing ribbon.

We .preferably mount on each type bar a small socket piece 7 in which is a spring 8 surrounding a plunger 9. The plunger is .held in the socket by a cap. 10, with its end 11 projecting to contact with the paper. Y As be the type bar is thrown'against the paper,

the plunger is forced into the socket, and as the type bar is raised, the spring will force the pins out of the papier, thereby stripping it, after which the type bar will be free to move away in the usual manner.v

Y The stripper will not be necessary in some instances, depending upon the nature of the paper and the number of the webs used.

It will be noted that in the Elliot-Fisher vmachine the inking ribbon isA carried by a holder which moves back and forth in a horizont-al plane beneath the printing point.

We use this operation in our machine.

., Thus on the carrier -12 reeipro'cated4 and 300 carried in a horizontal plane by the arm 13 point just above the position ofthe feltpiece, so that the felt wipes the nozzle formed by'said channels and the chamber casing.- f In operation the felt carrier swings the vfelt back and forth'so that thefelt wipes ink the type just before it makes its impression.v

The pins forming the type pass through l thefelt, thereby becoming inked, -and the 'fixed' ink supplying means located ,and-v ink rests on the surface of the pins, and is accumulated in the small grooves 01' veins in the points. c.

The.. pins then pass down through as many webs of paper as are used and form small ink outlined dots (Figure et) in-the'points 1We have, as stated, merely described onel embodinient'of ourinvention, the scope of which will be stated in the claims that follow.` l

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In. a manifolding'machine, the combination of a typewriter having itstype bars faced with type'in the form of pointed pins having the arrangement of the desired letter or symbol, a well for ink having a port andv a pad movable as in the caseof the ribbon holderin a typewriter to wipe the ink port of the well and project into interposition between the typeface andthe Webs vto be penetrated b the pins.

2. In com ination, a platen for a plurality of Webs of paper, a member movable to and Vfrom the prlnting point on said Webs,

a typewriter having type bars movable tol and from said point, said bars having type,`

faces formed of pointed pins, said movable member comprising a penetrable inking pad through which. the pins will pass and a adapted to supply ink to the penetrated portion of the pad when withdrawn from the printing print. y i l 3. In combination, a platen for a pluralityof Webs of paper, a member movable to and from the printing point on said Webs, a typewriterhaving type bars movable to -and from said point, said bars having type faces formed of pointed pins, Said movable member comprising a penctrable inking pad through which the pinsv will pass, and a resilient 4member on the .type bar adapted to force it away from the platen. l

4. In a manifolding typewritmg machine,

'the combination of a type base having a face formed of vpointed pins arranged to project in the formof a desired letter or symbol, and an inking device adapted to deposit ink on said pins, and means connected with the type base and having resilient action to force the base away from projected position of said base.

5i In combination, in a typewriter, Aa type bar having a type face formed of projecting pointed pins, means for inkingfsaid pins, and a spring contact or the like on the type bar adapted when the type bar is forced against a platen to project it away from the ^p1aten, thereby pulling thepin pointsl out of web material thereon.

6. A typel bar for machines of the character described, comprising the bar proper,

a type face formed of projecting pointed pins arranged in the form of a desired letter orsymbol, and a resilient platen contact on the bar adapted to force the bar away from al platen whenit strikes the same.

7. A type bar for machines of the character described, comprising thel bar proper,

`a type face'formed of 4projecting pointed pins arranged in the form of a desired letter or symbol, and a resilient platen contact on thebar adapted to force the bar awa from a` platen when it strikes the same, sai 4resilient contact device comprising a spring plunger mountedA on the type bar and projecting alongside'of the pins.

8. An inlzing device for Jprojecting pin type faces, comprising a rocking member,

vso

operable as an ink ribbon guide, an ink well having a port, a pad liolder on the rocking member having a cut-away space,a penetrable pad mounted on the holder and lying over sald cut-away portion, and said rocking member adapted to move the pad vin constant wiping contactwith the ink well port.
